Abstract

The application discloses a method and a device of improving code execution performance, and simultaneously discloses a method and a device of generating correspondence relationships of variable identifiers and types, and a method and a device used for generating source code containing type marking statements. The method of improving the code execution performance includes: acquiring the correspondence relationships which are pre-generated for the source code and of the variable identifiers and types; and compiling the source code, which is stored in a syntax tree format, according to the correspondence relationships to generate executable code after variable type limitation. By adopting the above-mentioned method, the variable types can be limited according to the pre-generated correspondence relationships when the source code is compiled, the executable code after variable type limitation can be generated, and thus memory space occupied by the executable code can be reduced; and processes of judgment for all the possible types are reduced, thus an execution rate of the executable code is also accordingly increased, and the overall execution performance is enabled to be improved.

Description

technical field [0001] The present application relates to the technical field of software development, in particular to a method and device for improving code execution performance. The present application also relates to a method and device for generating correspondence between variable identifiers and types, and a method and device for generating source codes including type annotation sentences. Background technique [0002] Programming language (programming language) is a formal language used to define computer programs. It is commonly known as "computer language". In a strongly typed language, there are many types of variables, such as int, char, float, boolean, etc., and the type must be clearly specified when defining a variable; in a weakly typed language, the variable type is usually not specified when defining a variable, and the variable is compiled It is also impossible to accurately deduce the variable type. "Weak typing" brings flexibility and convenience to d...
